Description

A directional antenna angle adjustment device

technical field

The invention relates to the technical field of communications, in particular to a device for adjusting the angle of a directional antenna.

Background technique

The pitch angle of the existing plate antenna is mostly adjusted manually. When the pitch angle needs to be adjusted, it is necessary to loosen the connection between the upper connecting component and the pole with a wrench, and then manually push the upper part of the plate antenna away from the pole. move in the direction. When the adjustment is completed, the upper connecting assembly needs to be tightened with a wrench. Because the poles are mostly installed on the platform at the top of the tower, the distance from the ground is usually about 45 meters, and it is dangerous to work at such a height. brought a lot of inconvenience.

In view of the above problems in the prior art, the present invention provides a device for adjusting the angle of a directional antenna, which can easily adjust the pitch angle of the plate antenna, does not require technicians to climb the tower to perform operations, and can improve the safety factor of technicians' operations .

The invention provides a device for adjusting the angle of a directional antenna, comprising a vertically arranged holding pole and a platform, the holding pole is fixedly connected to the antenna body through an upper connecting component and a lower connecting component, and the middle of the platform is fixedly provided with a fan-shaped The ratchet sheet, the lower end of the holding rod is hinged with the lower part of the fan-shaped ratchet sheet, and the holding rod is sequentially fixed with a connecting seat and a cylinder with covers at both ends on the right side of the lower part of the lower connecting assembly. A pulley is provided; the cylinder is provided with a spring matching its inner diameter and a cylindrical slider in sequence from top to bottom, the lower end of the slider is fixedly provided with a ratchet, and the ratchet passes through the lower end of the cylinder The cover plate is matched with the tooth slot of the fan-shaped ratchet plate, the upper end of the slider is connected with one end of the rope, and the other end of the rope passes through the cover plate on the upper end of the cylinder and goes around the pulley.

The platform is vertically provided with a limit block on the left side of the holding rod, and the limit block is set near the hinge point of the lower end of the holding rod to limit the maximum angle of the holding rod from rotating to the left.

A spring seat 1 is arranged on the left side of the lower part of the holding rod, and a spring seat 2 is arranged on the left part of the platform, and the spring seat 1 and the spring seat 2 are connected by a tension spring.

In the present invention, the lower end of the pole is hinged with the fan-shaped ratchet plate on the platform, and the pole is provided with ratchet teeth that can be pulled by ropes to control the rotation angle of the pole relative to the platform, so that the pitch angle of the antenna body can be changed. In this way, the pitch angle of the antenna can be adjusted, so that the rope can be extended to the bottom of the tower, so that there is no need for technicians to climb the tower to perform dangerous high-altitude operations, which can effectively improve the safety factor of technicians.

Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, a directional antenna angle adjustment device includes a vertically arranged holding pole 4 and a platform 5. The holding pole 4 is fixed to the antenna body 1 through an upper connecting assembly 2 and a lower connecting assembly 3. Ground connection, the forward covering direction of the antenna body 1 is to the right, the middle part of the platform 5 is fixedly provided with a fan-shaped ratchet sheet 6, the lower end of the holding rod 4 is hinged with the lower part of the fan-shaped ratchet sheet 6, and the holding rod 4. A connecting seat 7 and a cylinder 8 with covers at both ends are sequentially fixed on the right side of the lower part of the lower connecting assembly 3. The connecting seat 7 is provided with a pulley; A spring 9 with a matching inner diameter and a cylindrical slider 10, the lower end of the slider 10 is fixedly provided with a ratchet 11, the ratchet 11 passes through the cover plate at the lower end of the cylinder 8 and the teeth of the sector-shaped ratchet plate 6 The upper end of the slider 10 is connected with one end of the rope 12, and the other end of the rope 12 passes through the cover plate on the upper end of the cylinder 8 and goes around the pulley.

The platform 5 is vertically provided with a limit stop 13 on the left side of the holding pole 4, and the limit stop block 13 is set near the hinge point of the lower end of the holding pole 4 to limit the maximum angle of the holding pole 4 to rotate to the left to be 90°. Spend.
